SPECIFICATION forming part of Letters Patent No. 614,744, dated November22, 1898.

Application filed September 20, 1897. Serial No. 652,229. (No model.)

To all whom t may concern.-

Beit known that I, FREDERICK W. NET- TLETON, of New Haven, in the countyof New Haven and State of Connecticut, have invented a new ImprovementinSprayers; and I do hereby declare the following', when taken inconnection with the accompanying drawings and the letters of referencemarked thereon, to be a full, clear, and exact description of the same,and which said drawings constitute part of this specification, andrepresent, in-

Figure l, a sectional view of a sprayer embodying my invention; Fig. 2,a side view of the nipple detached; Fig. 3, a side view of the flexiblevalve-ring detached, and Fig. et a sectional view on line 4. 4 of Fig.l.

This invention relates to an improvement in sprayers, and particularlyto that class in which the liquid is contained in a flexible bulb, bythe compression of which the contents is ejected through thev nozzle.While the device is applicable for many purposes, .it is intended forthe use of bicycle-riders for throwing ammonia or other liquids at dogsor other troublesome animals.

The object of the invention is to produce a simple device which may bereadily operated and from which the liquid in the bulb may be ejectedwithout inverting the bulb 5 and the invention consists in theconstruction, as will be hereinafter described, and particularly recitedin the claims.

For convenience of illustration I have shown the device upon an enlargedscale, but the bulb A will be formed from flexible rubber and of a sizeconvenient to be grasped in thehand and, if desired, carried in thepocket. The bulb is oval or contracted at its ends, and in one end isinserted a nipple B, having a central passage, which is enlarged at theupper end, forming a seat b. Midway of its length is an annular flangeC, against the under edge of which the upper edge of the bulb will beseated, and preferably the lower end of the nipple will be formed withan annular shoulder D, over which the neck of the bulb vwill be drawn tosecure atight joint between the nipple and the bulb, which may becemented, threaded, or otherwise secured. The upper end of the nipple isexteriorly threaded,

lthrough the outer endof the nozzle.

and upon one side the surfaceis flattened, as at d, and through theflattened side of the nipple is a hole or perforation c. In the upperend of the nipple is located a ring E, of flexible rubber, which issupported in position by the shoulder l). This ring closelyfits theinterior of the upper end of the nipple and so as to normally close thehole e. Preferably the lower end of the ring E, beneath the hole c, willbe formed with a notch F, the purpose of which will hereinafter appear.The nozzle G will be provided with a collar II, interiorly threaded forengagement with the nipple, and the stem passes through the nipple andis of such a length as to extend into the contracted lower end of thebulb. Preferably the outer end of the nipple will be curved and adaptedto receive a closing-tip I. This tip may be of rubber and so as tofrictionally engage with the end of the nozzle, or may be made of metaland threaded for engagement with threads on the end of the nozzle, andfor convenience the tip I will be connected by a chain or cord J withthe nozzle G or collar H.

IVhen it is desired to use the device, the tip I is removed, and if itis made of rubber this can be conveniently done by striking it against apart of the cycle. Then upon the compression of the bulb the materialtherein will be forced outward through the stem and ejecticld As t ebulb is th-us compressed the material or air in the upper end of thebulb will be forced against the inner surface of the rubber ring E andpress that ring against the inner wall of the nipple, so as topositively close the hole e therein; but when the-bulb is released thepressure upon the ring is relieved and so that air may enter through thehole c and pass downward between the inner Wall of the nip- 'ple and theouter wall of the ring and escape beneath the lower end of the ring orthrough thenotch F therein into the bulb. In case the tip is notreplaced until after the bulb is expanded a sufficient amount of air mayenter through the nozzle; but it is desirable that a valve'should bearranged in the nipple for the inlet of air. As the inner end iscontracted and the stem of the nozzle extends ICO into the contractedportion, it follows that if held in an upright position practically theentire contents of the bulb may be ejected.

It will thus be seen that a device is produced which is readily carriedby cycle-riders, one which is conveniently operated and from which mostof the material in the bulb may be' ejected without invertingr thedevice.

I am aware that flexible bulbs have been used in connection with nozzleswhich extend into or through the bulb, and therefore do not wish to beunderstood as claiming, broadly, such as my invention.

Having fully described my invention, what l claim as new, and desire tosecure by Letters Patent, is

1. The herein-described sprayer com prising a flexible bulb having acontracted inner end, and an opening at the opposite end, anexternally-threaded nipple secured in the said open end and formed witha central longitudinal opening, a nozzle having a stein extendingthrough said nipple into the contracted portion of the bulb, a collarpermanent-ly secured to said stein, and internally threaded forengagement with said nipple, whereby the inner end of the stein ispositively located in the contracted portion of the bulb, substantiallyas described.

2. The hereindescribed sprayer,co1nprising a flexible bulb open at oneend, a nipple secured in the said open end and formed with a centralopening, the outer end of which is enlarged, the upper end of saidnipple exteriorly threaded, a transverse hole in one side of said upperend, a flexible rubber ring within the enlarged upper end of saidnipple, and a nozzle having a stem extending into said bulb and formedwith a collar interiorly threaded for engagement with said nipple,substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
